Installing the cage nuts in a 7014-S25 or 7014-S11 rack

You might need to install cage nuts into a rack. Use the procedure in this section to perform this task.

You must use cage nuts for all optional devices that do not have threaded holes. A supply of cage nuts is included with the rack. Cage nuts are installed on the inside of the rack-mounting flanges with either the cage-nut-insertion tool or a flat-blade screwdriver. The cage-nut-insertion tool comes with the rack and some optional devices.

To install the cage nuts with the cage-nut-insertion tool, complete the following steps.

Mark the precise place where you will mount optional equipment. For more information see, Install the system unit or expansion unit into a rack then return to these instructions.
